Aims:
To compare the clinical characteristics of Type 2 diabetes (T2DM) between immigrants from the Middle-East and Swedish patients.
Methods:
The study group included 450 consecutive patients with T2DM, 379 Swedish-born aged 61 +/- 12 years and 71 patients originally from the Middle-East aged 50 +/- 11 years from the diabetes clinic of Malmo University Hospital.
Results:
Onset of diabetes had occurred 12 years earlier in the Middle-East immigrants compared with the Swedish-born patients (43 +/- 10 vs. 55 +/- 12 years, P < 0.001). Immigrants had lower fasting serum C-peptide [0.7 (0.1-2.6) vs. 0.9 (0.1-4.0) nmol/l, P = 0.013], lower homeostasis model assessment (HOMA)-beta[1.7 (0.1-9.1) vs. 2.7 (0.1-59.0), P = 0.010], lower HOMA-IR [0.4 (0.02-1.19) vs. 0.4 (0.01-2.8), P = 0.005] than the Swedish group. A first-degree family history of diabetes was reported in 61% of immigrants, compared with 47% of Swedish-born (P = 0.022).
Conclusions:
Immigrants from the Middle-East have an earlier onset, stronger family history and more rapid decline of pancreatic B-cell function than Swedish patients, suggesting that they have a different form of T2DM compared with Swedish patients.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
